Title: Method and apparatus for photo excitation refining and reflection apparatus therefor
Inventor: ISHIKAWA TOSHIAKI
IPC: B01D57/00
Filed: 1989-11-09
Abstract: PURPOSE:To separate one kind raw material element from raw materials containing impurities so as to heighten purity of the element by one-time operation by selectively exciting the raw material element. CONSTITUTION:Only one kind raw material element among impurity elements is excited to intermediate energy level by radiant energy radiation with at least one kind of frequencies. The frequency of the radiant energy is so selected as to almost agree with at least one frequency which corresponds to the energy difference between the intermediate energy level and a normal or metastable or both normal and metastable energy levels of the element without exciting the impurity elements. While the one kind element excited to one of the intermediate energy levels is in the intermediate energy level, radiant energy having at least one frequency same as or different from said frequency is radiated so as to excite the element further to a higher intermediate energy level or the ionization energy level from previous intermediate energy level without exciting the impurities.

Filed: 1990-10-31
Abstract: PURPOSE:To improve operating feeling contact of a cassette holder and to reduce an overstroke by constituting to draw the holder downward by the arm of a locking mechanism in holding of the cassette. CONSTITUTION:A cassette holder 11 is engaged to be held in contact through locking arm 14 of a locking mechanism and a pin 14a, and the holder 11 and a cassette are placed only by gravity on installing positions at this time. Then, the arm 14 is drawn down by a predetermined driving mechanism, and the holder 11 presses the cassette to the position by the drawing force. A leaf spring 12 is fixed to the holder to be drawn by the arm 14, and the spring 12 is brought into contact with the arm 14. When the holder 11 is drawn at a predetermined amount, the spring 12 is deflected to absorb the drawing amount under the arm 14. Thus, an overstroke is reduced to improve an operating feeling contact.

Abstract: PURPOSE:To improve a cutting effect by cutting an inner wall of a pipe as copying a circumferential surface of a cutting head inclusive of a cutting edge after a form of the inner wall of the said pipe when cutting the pipe inner wall by relative rotation between the pipe and the cutting edge inserted into this pipe. CONSTITUTION:A rotary driver 11 is operated, rotating a face plate 12, and simultaneously with this, a feed gear 14 is moved to the left at constant speed, inserting a boring head 2 into a steel pipe A, and a cutting tool 3 cuts an inner wall of this speel pipe A by means of rotation of the steel pipe A and feed of the head 2. At a cutting process, the head 2 is held in the steel pipe A after a form of the inner wall of the steel pipe A by a copying shoe 6. In brief, even in the case where the inner wall is decentered and not in roundness, the head 2 is positioned right in the steel pipe A with the inner wall as a criterion. Accordingly, cutting allowance by the cutting tool 3 comes constant over the whole circumference of the inner wall, so that such uniform cutting that is nothing of any noncutting and over-infeed or the like is made possible and, what is more, surface roughness is also held down to the lowest possible extent.

Title: Liquid jet recording head
Inventor: KYOGOKU HIROSHI
IPC: B41J2/075
Filed: 1985-12-27
Abstract: PURPOSE:To make the deflection of the scattering direction of a liquid drop possible, by possessing the excitation means by which a head body is vibrated at a specific frequency and a specific amplitude. CONSTITUTION:An excitation means 2 consists of the element being vibrated by electric or electromagnetic control. A head body 1 is vibrated in recording at a specific frequency and a specific amplitude along the vertical direction shown by arrows u, d, that is, the subscanning direction by this excitation means 2. Then, the scattering direction of the ink drop jetted from each orifice O of the head body 1 is deflected along its vibration direction by this vibration. Thereby, a plurality of dots can be recorded along the subscanning direction as to one orifice. In this case, because the direction of vibration and the magnitude of acceleration differs according to the timing during one cycle, the deflection can be controlled by adjusting the jet timing of an ink drop 5 to this one cycle, the pitch among a plurality of dots can be controlled and the recording can be carried out by the density larger than the density of the orifice O.

Title: Photographic lens with movable lens group
Inventor: KITAGISHI NOZOMI
IPC: G02B27/64
Filed: 1987-11-20
Abstract: PURPOSE:To limit the quantity of off-axis luminous flux and to obtain a well- balanced light quantity distribution by moving a luminous flux limiting member at right angles to the optical axis when moving the movable lens group at right angles to the optical axis. CONSTITUTION:When the movable lens group V is made eccentric in parallel at right angles to the optical axis, the luminous flux limiting member P is moved in the opposite direction from the moving direction of the movable lens group V on condition that the movable lens group V has positive refracting power. Consequently, one piece of luminous flux can be cut off, so a decrease in optical performance which is caused when the blur of an image is corrected is corrected by using the luminous flux limiting member P. Consequently, the invariably well-balanced light quantity distribution is obtained and an excellent image is obtained.

Title: Electrically conductive elastic roller and its manufacture
Inventor: SUZUKI MICHI
IPC: B29C45/14
Filed: 1987-11-20
Abstract: PURPOSE:To firmly maintain the electrical connecting property to a mandrel with low hardness without being influenced by an elastic deformation, etc., by forming the title roller by a thermoplastic elastomer formed as one body between a first conductive layer and a second conductive layer, and a thin connecting wall part to which a conductive filler is added. CONSTITUTION:As for a core layer 11 consisting of a thermoplastic elastomer resin, no conductive filler is added, therefore, the core layer 11 can be set to low hardness. Also, hardness of a first conductive skin layer 10, a second conductive skin layer 12, a connecting wall part 13 and the whole conductive elastic roller can also be made roughly equal to hardness of the core layer 11. Accordingly, the conductive elastic roller can be connected electrically to the second conductive skin layer 12 and the first conductive skin layer 10 through the connecting wall part 13, and also, as for the connecting wall part 13, the part between both the conductive skin layers 10, 12 is formed into one body extending over its overall length, a conduction failure by an elastic deformation, etc. is not generated, and desired hardness is obtained. In such a way, the reliability of the electrical connection of the mandrel and the surface of the roller is improved remarkably with low hardness.

Title: Analysis of contamination quantity in process
Inventor: ADACHI NOBUO
IPC: C03C3/072
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To produce optical glass and high performance glass stably by facilitating to grasp and manage the contamination quantity of impurities produced from the production system of glass through a structure where the detection limit of specific element in the glass is 0.1ppm or below. SOLUTION: When a solution of glass for analyzing the process contamination quantity, i.e., SiO2 -B2 O3 -PbO, is subjected to quantitative analysis, disturbance components of glass composition (matrix components) can be removed entirely. SiO2 is an oxide for forming the glass and enhances chemical resistance and B2 O3 is also an oxide for forming the glass and enhancing solubility. PbO is an element which can be introduced in large quantity and it is introduced in order to control the properties of glass, e.g. viscosity. When the SiO2 , B2 O3 and PbO components are removed entirely from the glass composition and the supernatant is analyzed, a solution dissolving only the impurities and ensuring highly accurate analysis is obtained.  Consequently, trace impurities can be analyzed up to a concentration region which can not be dealt with by a conventional method and the mixing amount of impurity can be grasped during the dissolving process.
